Driving monitor via USB info

[Ch3m1c4L]

Can someone relieve my ignorance on this concept please.
I know the port needs to support dp/hdmi via USBc, although not sure if this is standard in 3.1 or 3.2 if a c-type port?

Does the c port on my x570 Asus crosshair viii hero support it, even though I can't see it explicity mentioned on the spec sheet?

Does the host system require the use of an igpu or can it be driven via a discrete card? Or is it all just software emulation?

Is it a solution to going beyond the max monitor support of the igpu/dgpu (4?) or does it encounter the same limitations and is just a different interface, which the benefit of is simply less cabling for specific displays?

Thank you both. That has cleared up my confusion/understanding of what it is and how I can use it.

just read my manual
looks like 15w on the rear ports
and 60w on the front port
though cant do video off front port i think
dont have my front port connected as gpu is massive
and blocked it
but 15w on rear doesnt sound enough
to power a monitor
though can send video
must admit its pretty confusing
theres no hdmi or display port out on rear io only IN
so even though the board supports G cpus
i see no way to actually use their integrated graphics
though i am having a bit of a brain dead day i must admit

That's a bit annoying, means you have to dp from gpu to mobo, just to then usbc to monitor, but carrying no power on so at most only saving running a usb data cable to the monitor. Seems like an after thought in the design rather than allowing the 60w pd to go via rear port.

I think with these higher end boards, one isn't expected to pairing it with a low end cpu, which all apus were/are. You'd buy a cheaper board if you were buying a cheaper cpu. So it saves a little on cost I imagine.

Little annoying though when it comes to many monitors, but I guess it's niche enough that people can be expected to research/buy specific product versions. May well change in future as the range of amd cpu's with igpu's changes/increases.
